Deploy containers to Azure App Service
In this tutorial, you use Visual Studio Code to create a containerized Node.js application using Docker, push the container image to a registry, and then deploy the image to Azure App Service.
- An Azure subscription.
- Visual Studio Code.
- The Docker extension
- The Azure App Service extension
- Node.js and npm, the Node.js package manager.
If you don't have an Azure subscription, sign up now for a free account with $200 in Azure credits to try out any combination of services.
Sign in to Azure
Once you've installed the Azure extension, sign into your Azure account by navigating to the Azure explorer, select Sign in to Azure, and follow the prompts. (If you have multiple Azure extensions installed, select the one for the area in which you're working, such as App Service, Functions, etc.)
After signing in, verify that the email address of your Azure account (or "Signed In") appears in the Status Bar and your subscription(s) appears in the Azure explorer:
If you see the error "Cannot find subscription with name [subscription ID]", this may be because you are behind a proxy and unable to reach the Azure API. Configure
HTTPS_PROXY environment variables with your proxy information in your terminal:
# macOS/Linux export HTTPS_PROXY=https://username:password@proxy:8080 export HTTP_PROXY=http://username:password@proxy:8080
# Windows set HTTPS_PROXY=https://username:password@proxy:8080 set HTTP_PROXY=http://username:password@proxy:8080
Verify Docker install
Verify that you have Docker installed properly by running the following command in a terminal or command prompt:
The output should appear something like the following:
Docker Version 17.12.0-ce, build c97c6d6
